[0003] A Chinese patent with publication number CN116851861A discloses a diverter welding device and a control method thereof, including a device body, wherein a processing space is formed in the device body, and the device body is provided with a vacuum unit, wherein the vacuum unit is used to vacuum the processing space, and the device body is defined to have a height direction; a heating mechanism, wherein the heating mechanism is arranged in the processing space, wherein the heating mechanism is used to heat a first processing workpiece; and a pushing mechanism, wherein the pushing mechanism is arranged in the processing space and above the heating mechanism, wherein the pushing mechanism is used to drive the second processing workpiece to move toward the first processing workpiece. Although the device can process bubbles, it cannot recycle the waste gas generated by the melting of the welding ring.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] First embodiment like Figures 1 to 7As shown, the present embodiment discloses an air-conditioning diverter welding ring device, including a positioning ring 1. The cross-section of the positioning ring 1 is C-shaped. The positioning ring 1 adopts an open design and can directly pass through the workpiece for welding without being inserted from the upper end of the welded workpiece. It is more convenient to use and can prevent the upper end of the welded pipe from being too large in diameter and unable to be inserted. A mixing component 2 is provided inside the positioning ring 1. When the mixing component 2 rotates, it can drive the nearby hot gas to rotate, so that the welding ring can be continuously and evenly heated by the rotating hot steam to avoid local overheating. A first heating ring 3 is provided at the lower part of the inner wall of the mixing component 2, and a control end 4 is provided on the rear side of the positioning ring 1. The control end 4 is made of ceramic fiber as a whole to avoid overheating during the welding process. The control end 4 is melted, and the control end 4 is mainly used to control the overall position, making it more convenient to use. An adjustment component 5 is provided on the upper surface of the positioning ring 1, and a second heating ring 6 is provided on the inner wall of the adjustment component 5. The adjustment component 5 can change the angle between the second heating ring 6 and the positioning ring 1, so that the second heating ring 6 can heat the upper surface of the welding ring, and by changing the heating direction, the heating is more uniform. The first heating ring 3 and the second heating ring 6 are both resistance heating rings, and an independent power supply is provided inside. The resistance heating ring is composed of a resistance wire and an insulating material. When the power is turned on, the current passes through the resistance wire, and the resistance wire generates heat due to its own resistance. The generated heat is transferred to the heated object by heat conduction, thereby heating the object.

[0025] The mixing assembly 2 includes a first rotating ring 201 for collecting gas. The inner wall of the first rotating ring 201 is inclinedly provided with a plurality of blades 202. When the first rotating ring 201 rotates, it can drive the blades 202 to change the direction of the hot gas, so that the hot gas can slide and heat along the surface of the workpiece, avoiding heating the same position for a long time to cause gasification. The blades 202 are inclined, so a part of the gas can be driven by the blades 202 to rotate, and the other part of the gas can directly pass over the blades 202 under the action of the inclined surface, avoiding the hot gas of this part to be taken away, resulting in cooling and uneven heating of the welding ring. The inner wall of the first rotating ring 201 is provided with a plurality of air inlet holes 203, which are located at the lower side of the axial position of the first rotating ring 201, so that the air inlet direction is filled from the lower side to the inside of the cavity 204. When the first rotating ring 201 rotates, it can drive the air inlet holes 203 to collect part of the gas (the welding ring is usually a tin-lead welding ring. During the welding process, when the welding ring melts, lead may be released into the air in the form of steam or smoke. When the human body inhales these lead-containing steam or smoke, the lead will accumulate in the body, which will damage the nervous system, blood system, digestive system, etc.), thereby achieving the purpose of collecting waste gas.

[0026] The adjustment assembly 5 includes two symmetrical hinge seats 501, and a second rotating ring 502 is hinged between the two hinge seats 501 through a pin shaft. The second rotating ring 502 can rotate along the hinge seat 501 as the center, thereby changing the angle between the second rotating ring 502 and the positioning ring 1, thereby driving the second heating ring 6 to change its position and gradually approach the upper surface of the welding ring, so that the upper surface can be heated. This heating position is close to the inner ring of the welding ring, which can make the inner ring of the welding ring melt first, so that the molten solder melt fits the gap of the connection, and is fixed more firmly after cooling. At the same time, since the gap is filled, the sealing performance can also be improved. A guide block 503 is provided in the middle of the inner wall of the second rotating ring 502, and the cross-section of the guide block 503 is triangular.

[0027] It should be noted that when the guide block 503 rotates following the second rotating ring 502, under the guidance of the guide block 503, the direction of the hot air can be changed so that the hot air moves closer to the workpiece along the trajectory of the guide block 503, thereby avoiding hot air dispersion which is not conducive to rapid heating and affects the overall welding efficiency.

[0028] A cavity 204 is provided inside the first rotating ring 201, and the cavity 204 can accommodate gas. When rotating, part of the gas is introduced into the cavity 204 through the air inlet 203. When collecting the gas, the generated waste gas can be absorbed, thereby protecting the operator and avoiding damage to the human body due to absorption. The cavity 204 is connected to each air inlet 203. A concentration sensor is provided inside the cavity 204, and the concentration sensor can detect the waste gas content inside the cavity 204 in real time (the waste gas refers to lead in this case, and the concentration sensor can detect the lead concentration). The waste gas concentration gradually increases, indicating that the welding ring is partially vaporized, but part of it fails to melt, and thus the heating method needs to be adjusted so that it can be heated evenly.

[0029] Two symmetrical airbags 205 are provided at the front end of the first rotating ring 201, and the airbags 205 are connected to the cavity 204. The airbags 205 can collect the waste gas and hot gas generated by each processing to prevent the waste gas from being discharged. The airbags 205 are provided with a discharge port. When the interior is saturated, the exhaust gas inside can be discharged through the discharge port. A one-way pressure valve is provided between the airbags 205 and the cavity 204. The one-way pressure valve can allow the gas to pass through, but cannot flow back, so that the gas can be collected.

[0030] The cavity 204 is internally slidably connected with a first push plate 206, the size of which is consistent with that of the cavity 204, and the cavity 204 can be evenly divided into an upper space and a lower space. A plurality of springs are provided on the bottom surface of the first push plate 206, and the lower end of each spring is fixedly connected to the inner bottom wall of the cavity 204. With the support of the spring, the first push plate 206 is in a suspended position, and the lower space is connected to the air inlet 203, so that the gas can enter the lower space through the air inlet 203 but cannot enter the upper space. The spring can play a certain supporting role. A first magnet ring 207 is provided on the upper part of the first rotating ring 201, and a plurality of push rods 208 are provided on the upper surface of the first push plate 206. The upper end of each push rod 208 is fixedly connected to the bottom surface of the first magnet ring 207.

[0031] It should be noted that when the gas in the lower space gradually increases, the air pressure can push the upper first push plate 206 to gradually move upward. Under the action of the first push plate 206, multiple push rods 208 can be driven to move upward. At the same time, the spring can be stretched to generate a restoring elastic force. Under the thrust of the push rod 208, the first magnet ring 207 can gradually rise, and the first magnet ring 207 can be close to the second magnet ring 9, so that a magnetic attraction is generated between the two. Driven by the magnetic attraction, the first magnet ring 207 and the second magnet ring 9 move synchronously.

[0032] A first circular arc groove 7 is provided on the inner wall of the positioning ring 1. Under the constraint of the first circular arc groove 7, the mixing component 2 can perform circular motion along the trajectory of the first circular arc groove 7. The mixing component 2 is arranged inside the first circular arc groove 7. The cross-section of the mixing component 2 is in a 7-shape. Through the 7-shape arrangement, the mixing component 2 and the first circular arc groove 7 can always be at the same center of a circle, thereby avoiding interference caused by misalignment during rotation.

[0033] A second arc groove 8 is provided on the upper surface of the positioning ring 1, and the second arc groove 8 can constrain the position of the second magnet ring 9 to avoid misalignment under the action of centrifugal force. The second magnet ring 9 is slidably connected inside the second arc groove 8, and the second magnet ring 9 and the first magnet ring 207 are magnetically attracted to each other. The upper surface of the second magnet ring 9 is fixedly connected to the bottom surface of each hinge seat 501.

[0034] It should be noted that when the first magnet ring 207 gradually rises, a magnetic attraction force is generated between the first magnet ring 207 and the second magnet ring 9, so that the second magnet ring 9 can follow the first magnet ring 207 to perform circular motion, driving the two hinge seats 501 to perform circular motion.

[0035] A mounting plate 504 is provided on the right side of the hinge seat 501 on the right side, and a first motor is provided on the upper surface of the mounting plate 504 . The output end of the first motor is fixedly connected to the pin shaft.

[0036] It should be noted that when the first motor is started, under the action of the output shaft, it drives the pin shaft to rotate, and under the constraint of the pin shaft, it drives the second rotating ring 502 to rotate along the pin shaft, so that the angle between the second rotating ring 502 and the positioning ring 1 gradually increases, and the position of the second heating ring 6 changes. The larger the angle, the closer the heat source is to the upper surface of the welding ring, so that the second heating ring 6 can heat the upper surface of the welding ring. At the same time, part of the heat source is close to the workpiece, and part of the heat is introduced into the inner side of the welding ring through heat conduction of the workpiece, so that the welding ring can be heated from the inside, thereby avoiding uneven heating.

[0037] The outer surface of the positioning ring 1 is provided with a plurality of adjustment cavities 10, and the inner top wall of each adjustment cavity 10 is provided with a second motor. The adjustment cavity 10 is used to accommodate the second motor, and the output end of the second motor is fixedly connected with a gear 11. The outer wall of the second rotating ring 502 is provided with a gear ring 12, and the gear 11 and the gear ring 12 are meshed.

[0038] It should be noted that the three second motors are started at the same time and have the same rotation speed, which can drive the three gears 11 to rotate at the same time. Under the action of meshing, the gear ring 12 is pushed to rotate at the same time. Since the gear ring 12 is semi-arc shaped and the arc is greater than one hundred and eighty degrees, when the gear ring 12 rotates to any position, there is always a gear 11 in contact to provide power for it.

[0039] The control end 4 includes a handle 401, which is made of ceramic fiber and can isolate most of the heat. The outer surface of the handle 401 is covered with an anti-slip cover 402, which is made of rubber material and can isolate the remaining heat, thereby protecting the hands and avoiding burns. A positioning frame 403 is provided at the front end of the handle 401, and two symmetrical arc-shaped suction cups 404 are provided on the front of the positioning frame 403, which are connected by adsorption, so that the positioning ring 1 of the appropriate size can be quickly replaced to avoid size mismatch. At the same time, replacement is faster and more convenient. The front of the two arc-shaped suction cups 404 is connected to the outer surface of the positioning ring 1, and the material of the positioning ring 1 is also composed of heat-insulating material to avoid being affected by high temperature.

[0040] Before use, select the corresponding positioning ring 1 according to the size of the workpiece to be welded, then weld the control end 4 and the positioning ring 1 together through the arc suction cup 404, then put the pipe to be welded into the welding ring, and then place the two on the surface of the workpiece so that the welding ring is at the connection.

[0041] When in use, the handheld control terminal 4 aligns the opening of the positioning ring 1 of the device with the pipe fitting and pushes it forward so that the pipe fitting and the positioning ring 1 are concentric, and the first heating ring 3 is energized to generate heat through resistance, and then the three second motors are started at the same time. Under the action of the second motors, the three gears 11 rotate synchronously, and under the action of meshing, the gear ring 12 is driven to rotate, so that the first rotating ring 201 rotates, and driven by the first rotating ring 201, the first heating ring 3 and the fan blades 202 are respectively moved along the trajectory of the first circular arc groove 7. Under the action of the rotating first heating ring 3, the position of the heat source can be kept moving to avoid local overheating or inadequate heating. Under the action of the rotating fan blades 202, the hot air can be pushed to rotate, so that the hot air can be conducted along the surface of the welding ring, so that the welding ring is heated more evenly.

[0042] Driven by the first rotating ring 201, the air inlet 203 is driven to rotate. With the cooperation of the rotating air inlet 203 and the fan blades 202, part of the hot air can be introduced into the cavity 204 through the air inlet 203, so that the hot air can be absorbed. At the same time, during the absorption process, the waste gas generated by the melting of the welding ring can be absorbed to avoid damage to the operator.

[0043] When the concentration sensor detects that the concentration reaches the threshold, it indicates that the lower end of the outer ring of the solder ring has been melted, and part of the melted solder liquid has vaporized to produce toxic gases, and the following adjustments are required: As the first rotating ring 201 continues to rotate, the gas entering the cavity 204 through the air inlet 203 gradually increases. Under the action of the air pressure, the first push plate 206 is pushed to gradually move upward. Under the action of the push rod 208, the first magnet ring 207 is driven to gradually rise until a magnetic attraction is generated between the first magnet ring 207 and the second magnet ring 9, so that the second magnet ring 9 can move with the first magnet ring 207.

[0044] When magnetic attraction is generated between the two, the temperature generated by the first heating ring 3 is reduced to prevent excessive vaporization of the molten solder at the lower end, and at the same time, the second heating ring 6 is started to heat the upper end of the welding ring. Under the action of the magnetic attraction of the first magnet ring 207, the second magnet ring 9 above is driven to rotate. Under the constraint of the two hinged seats 501, the second rotating ring 502 drives the second heating ring 6 to rotate with the second magnet ring 9, and the upper end of the welding ring is evenly heated by rotation.

[0045] When the second rotating ring 502 rotates, it can drive the guide block 503 to rotate. Under the guidance of the guide block 503, a strong hot air flow can be generated and approach the welding ring. This strong air follows the rotation of the second rotating ring 502, so that the welding ring is heated more evenly.

[0046] At the same time, driven by the first rotating ring 201, the fan blades 202 and the air inlet 203 rotate accordingly. Driven by the fan blades 202, a rotating airflow is generated to rotate along the workpiece, thereby slowing down the falling speed of the solder melt at the lower end, avoiding excessive spread of the solder solution here and affecting the strength after welding. At the same time, since the first heating ring 3 is closed at this moment, the temperature of the lower end is reduced, and the fan blades 202 rotate to fan the air, which can speed up the cooling time of the lower end and enable the lower end to be welded first, thereby achieving the purpose of positioning and avoiding the subsequent welding ring from being completely melted and misaligned.

[0047] As the first rotating ring 201 continues to rotate, the gas entering the cavity 204 through the air inlet 203 increases again. Under the action of air pressure, the first push plate 206 has been moved to the extreme position. At this time, the pressure inside the cavity 204 gradually increases, causing the one-way pressure valve to open, so that the airbag 205 and the cavity 204 are connected. Part of the hot air can enter the airbag 205 through the one-way pressure valve, collect the exhaust gas, and reduce damage to the operator.

[0048] When the concentration sensor detects that the concentration reaches the second threshold, it indicates that the upper end of the outer ring of the solder ring has been melted, and part of the melted solder liquid has vaporized to produce toxic gas, and the following adjustments are required: Start the second motor, and under the action of the second motor output end, drive the pin shaft to rotate, so that the second rotating ring 502 rotates along the pin shaft, so that the angle between the second rotating ring 502 and the positioning ring 1 gradually increases, so that the part of the second heating ring 6 close to the guide gradually approaches the workpiece and the inner side of the welding ring, and part of the heat of the second heating ring 6 is transferred to the surface of the workpiece. Under the action of heat exchange, the heat can be introduced into the inner ring of the welding ring, so that it can accelerate the melting efficiency. Under the action of the second rotating ring 502, the guide block 503 is driven to rotate continuously. Under the guidance of the guide block 503, a strong hot air flow can be generated, approaching the upper end of the welding ring to avoid the situation of insufficient heating due to the distance being too far. This part of the heat heats the upper surface of the welding ring. This position is closer to the inner ring relative to the outer ring of the welding ring, so that the melting of the inner ring can be accelerated when it is heated, avoiding the situation of insufficient heating and affecting the welding strength.

[0049] At the same time, under the action of the first rotating ring 201, the fan blades 202 and the air inlet continue to work to collect the exhaust gas.

[0050] When the welding is completed by naked eye, first reverse the second motor to reset the second rotating ring 502, cut off the power to the second heating ring 6, and drive the first motor to cool the workpiece through the fan blades 202. When the processing is completed, turn off the first motor to stop the first rotating ring 201 from rotating until it returns to its original position, and then remove the whole from the workpiece through the handle 401 to complete the welding.
